> The {{BlockingCallMonitoringThreadPool}} modifies the core/maximum pool size
> of an underlying executor. It always first modifies the core size, and then
> the maximum size. When increasing the pool size it thus follows that core
> size at one point exceeds the maximum. This is fine on java 8, but no longer
> allowed on Java 9.
